      The solar system only has one star — the sun! The solar system is the name for our sun and all the things orbiting it. Our galaxy, the milky way, is a big group of stars and things orbiting them; it has between 200 and 400 billion stars at our best estimate.

      We just have one star in our solar system called the Sun. The solar system is all the planets, comets and asteroids that orbit the Sun.

      Some other star systems can have multiple stars. A system with two stars is called a binary system and we think that those are very common! We have found systems with up to 7 stars in them! but those are very rare (we only know of 2 I think)
